AUTOMOBILE GULTIVATOR.

Specification of Letters Patent.

To all whom it may concern: 7

Be it known that I, AnoLrriU's R. LYNCH, a citizen of the United States,and resident of Danville, in the county of Vermilion and 'State ofIllinois, have invented certain new .and useful Improvements inAutomobile Cultivators, of which the following is a specification.

The present invention relates to cultivating machines, and particularlythose of the vertical rotating type and has for its purpose to provide amachine of that character adapted to be propelled through the medium ofan explosive engine whereby to entirely eliminate the use of horse powertherefor.

A further purpose of the invention is to provide a machine of the typein question, whereby the rotary cultivators are at all times under theimmediate control of the operator to the extent that their rotarymovement maybe controlled at will and whose direction of travel may bevaried from their true course to avoid interference with the plants.

With 'the above objects in view, the inventionis described in fulldetail in the following specification and the novel. points i thereofset forth in the appended clalms.

In the accompanying drawings, which show the invention in its preferredstructure, Figure 1 is a top plan view thereof,

Fig. 2 is a side elevation of the same, and

Fig. 3 is a rear end elevation.

Referring now to the several figures more in detail and with likenumerals of reference indicating corresponding parts in the differentfigures shown, the invention comprises a vehicle whose frameisdesignated b l, w ard wheels thereof respectively. Said frame issuitably supported above the wheels by the uprights 2 and the pair offorks 3, whereby the vehicle may easily clear the plants to becultivated.

Suitably mounted upon the frame 1 is an engine 4 preferably of theinternal combustion type and 5 is the shaft driven thereby and 6the flywheel.' A chain 7 transmits power from the main shaft 5 to acountershaft 8 through the medium of a sprocket 9 that is mounted freeto rotate thereon. Said sprocket 9 is provided with a clutch element 10with which cooperates a like member 11 that is splined upon the shaft 8and pro vided with a lever 12 for moving the same and 2 and? are, therearward and for her 10. At its opposite ends'the shaft 8 is fitted withsprockets 13 upon which travel a pair of chains 14 that transmit powerto the wheels 2 through the medifim of sprockets 15 that are mounted onsaid wheels. The shaft 8 is also provided. with a'pa-ir of beveledpinions 16 disposed intermediate the end pinions l3, and which aresplined on said shaft. The pinions, 16 are adapted to mesh with a pairof like pinions 17 that are mounted upon counter-shafts 18. Said shafts18 are normally held in gearing relation with and are adapted to drivecounter-shafts 19, which in turn cause the rotation of-the cultivators20 through the gearing connections 21 asv clearly shown in Fig. 2. Saidcultivators, 20 are adapted to rotate counter-wise to the direction oftravel of the vehicle, and by so doing to throw the pulverizedearthin'wardly toward the row of plants over which the vehicle istraveling. To effect this latter condition,- the cultivators 20 areinclined rearwardly and toward each other and are provided with aplurality ofradially disposed teeth 38 and constitute the cultivatorsproper of the machine.

The means for mounting the cultivators comprise two Y-frames 23, the tworear members of which are provided with a reach The upright portions 23.or those parts of the frames that connect with the vehicle frame properare constructed with a double hinge 23 (see Figs. 2 and 3), whereby thecultivators may be changed or moved from or section 2a within which arejournaled the cultivators 20 as shown in Figs. 2 and 3.

their true path for the purpose'of avoiding obstacles, or plants thatshould happen to be to either side of the row that is being cultivated.For the purpcse of efiecting' this deflection of the cultivators, theframes thereof are each fitted with a handle 25 that is convenientlywithin reach of the. operator who sits in the seat 26. The shafts 19.arepreferably provided with knuckle joints 19 to give them freedom ofmovement.

In order that the rotation of the cultivators may be controlled at willby the opera-- tor, there .is provided a pair of handles or levers 27which serve to connect or disconnect the beveled gearings '16 and 17 ina manner that willbe obvious. A lever 28 disposed immediately in frontofthe seat 26 controls, through the rods 29, 30 and the bell cranks 31,the direction of the wheels 3 whereby to steer the machine. i

From the foregoing it will be seen that this machine will effectivelycultivate the ground to either side of the plant row and that suclrearthas has been removed intermediate the rows will be thrown in a morethemounting of said cylinder permitting of slight lateral displacementthereof, and means for imparting rotary movement to said cylinder.

1 2. A machine for cultivating the soil comprising a vehicle, a pair ofcylinders carry ing a plurality of teeth and mounted to' rotate in saidvehicle, said cylinders adapted to have slight lateral movement andbeing oppositely disposed toward the rear of the vehicle, and means forimparting rotary movement .to said cylinde: s direction of-travel of thevehicle. 3.-A machine for cultivating the soil comprising a vehicle, amotor for propelling opposite the the. vehicle, a pair of opposite andrearwardly disposed cultivators mounted in said vehicle and adapted tobe rotated opposite the direction of travel thereof, said cultivatorscomprising a plurality of radially disposed teeth carried by cylinders,means for permitting of separate or simultaneous rotationofthecylinders, and means for effecting lateral displacement of thecylinders whereby to move the pulverizing teeth clear of obstacles inthe path thereof.

4. A machine for cultivating the soil com-' prising a vehicle, a'motorfor propelling the vehicle, a pair of arms with. double joints indersthrough the operation of said motor.
